How Does the Dimple Design Improve Drainage?

The distinctive dimpled surface forms interconnected spaces through which water can move vertically or horizontally, depending on the installation arrangement. These channels help prevent water from remaining trapped against protected surfaces. The dimples also separate the board from the substrate, creating a drainage cavity. Some products include a geotextile filter layer that helps limit soil particles entering the drainage channels. This feature can support consistent water movement when selected appropriately for site conditions. Drainage capacity depends on dimple geometry, compressive strength, soil conditions, and installation quality. Therefore, selecting a suitable board for the project’s expected loads and drainage requirements is important.
